CD-ROM Blue Book – cdrom rom

The Blue Book defines the Enhanced Music CD specification for multisession pressed disc (i.e. not recordable) comprising audio and data sessions. These discs are intended to be played on any CD audio player, on PCs and on future custom designed players. The Blue Book comprises:

Disc specification and data format including the two sessions (audio and data)

Directory structure (to ISO 9660) including the directories for CD Extra information, pictures and data. It also defines the format of the CD Plus information files, picture file formats and other codes and file formats

MPEG still picture data format.

Otherwise known as CD-Extra or CD-Plus, Blue Book CDs contain a mix of data and audio, recorded in separate sessions to prevent data tracks being played on and possibly damaging home hi-fis.
